Good morning all;

I discovered a flat (Front, Driver side) yesterday and brought the tire to good old Walmart to have it patched up.

I was informed that the tire was not patchable, but since it was under warranty, it wouldn't cost me much to get a new tire replaced. I asked about if it was necessary to change the second tire too; he said that no, they change only 1 all the time...

However, I have always been under the impression that changing only one tire "is not good" but I can't seem to find anything that backs my argument up.

The other tire still at 9/16 tread depth...so is that 1/8th of an inch enought to make a difference?

Thanks,
Denis
